Subject: [PATCH 0/8] RPi touchscreen panel driver v4

The review for v3 was basically "no, the panel should probe first so
that we have the connector by the time KMS is done initializing."  To
do this, I needed to be able to register the custom (non-OF-generated)
DSI device without the host being present (patch 6).  Also check out
patch 4 for a new cleanup to panel-bridge.

Eric Anholt (8):
  drm/vc4: Fix DSI T_INIT timing.
  drm/vc4: Fix misleading name of the continuous flag.
  drm/vc4: Use drm_mode_vrefresh() in DSI fixup, in case vrefresh is 0.
  drm/bridge: Add a devm_ allocator for panel bridge.
  drm/vc4: Delay DSI host registration until the panel has probed.
  drm: Allow DSI devices to be registered before the host registers.
  dt-bindings: Document the Raspberry Pi Touchscreen nodes.
  drm/panel: Add support for the Raspberry Pi 7" Touchscreen.
